To all whom Muay concern.'

'Be it known that ISAAC KENsnL EVANS, a citizen of the United States, residing. at Hollinger, in the county of Lancaster `and State of Pennsylvania, has invented certain new and useful Improvement-s in Fuel Feed for-lVickless Burners, of which vthe following is a specifica-tion, reference being had therein to the accompanyingr drawing.

This invention relates to an oil feeding oi'l burners, such as are employed for heating broeders, oil stoves and anyv other uses where a -wiekless oil' burner isused.

I One of the objects of the invention is to provide means whereby is-maintainedat all times.

.Another object of theinvention is to providel meansfwhereby the Aflow of' eiland the oil level can be regulated without the use 0f valves, L f

Still another object being`that the oil level may be changed by the action of a thermostat, or may be regulated by positive adjustment by the operator. lV ith these and other objects in view my invention consists in certain construction and combination of pars as will hereinafter be fully described and claimed, and shown in the accompanying drawings which form a part of this application and in which like figures of reference refer to corresponding parts in all of the views, but it is :fully understood that whilel have claimed my invention shown that T do not confine myself to the exact construction as changes may bc made Without departing from the spirit of the invention. y

.In the drawings,

Figure 1 is a top plan View of my device as applied to a brooder.

Figure 2is a side elevation of the same.

Figure 3 is an enlarged view of the, con' trolling1 means, showing the same as actuated by a thermostat.

Figure 4 is a similar view showingr the same as actuated by a positive adjustment Referringto uthe drawings, the devre comprises an oil reservoir 1 of glass or other suitable material here shown asin the form of a bottle, and which may be provided with a band 2 and a bail handle Sifor carrying the same about.

The neck 4 of said reservoir Lis vprovided with a cap 5 having 4formed therein the a steady flow of oil through the small pipe taper hole 6 for the reception a 8 which is adapted to slide freely upland Y' down in a 'bearingv 9 which is secured to thev plug 7' being'y 6 by' `thel action of a vert-ed 'and placed `on the' topf of'. the oiil vchamber 12 thatthe end of saidrodB will formed 1in `a supportv 10., or a part of the cap 451;. normally 'inl aff closed position' with relation.toithe spring 11; buh the'.-

.length that when the reservoir 1 is l in-g come into contact with -the bottom .fof fthe chamber 12 in "such `a or force upward the plug` 7- 'and'openf the hole 6 allowing .they oil to feedfintosaidj chamber 12.

The oil' 'chamberl12 is'formed with a wall,- lf3 dividing said chamber. finto two parts and '1.5 {said wall extending, slightlyflabove". the oil level and havinga wick 'of suitable.

material placed 'thereon' with'v its .ends ,eX-

tendingdow'nward into""the chambers' .14,

and 15 vand thus jfedingf the oil from the chamber 14 into the chamber 15 by capillary attraction. f

F rom the bottom ofthe chamber 15a feed-pipe [6 is attached to an L A,fitting 17 and an upright pipe l18 connects to an-L itting'l).

manner. as to push Said fitting 19 is secured to one 'end o a large horizontal pipe 20 which has its ot er end secured to a `T7 fitting 21.

Within the pipe 20 and near the fitting 19 is rigidly secured a tight plug22 which is of any suitable oil tight material, and which' has near the bottom of the pipe 20 a tube 23 scoured therein. 1 'l This tube l23 is of sinalldiameter and of some springy material such as brassor steel and being rigidly secured at one end while its other end is free its l'ieeend can be de-V ieeted up and down like the free end of a spring.

The .oil in its passage through the feed pipes is prevented from pipe 20 by the plug Y ortube 23 which is placed in a slight upward angle inthe pipe 20; and the discharge end 'of said tube 23 is 'formed with a lip 33 to insure a dripof -the oil and prevent passage through the 22 and must travel ing the end ,of the tube 2 3 the oil level will l be changed.'

' typedesired.

As the oil leaves the disehargevend ofthe tube 23 it, descends through the T fitting 2l the pipes25 and 26 and L fitting 24 to the any suitable burner 27,- which may be of ',For regulating the oil level or the `posi- .tion of the dischargeend of the tube 23 there'is provided an Aadjusting screw 2 8 threaded yinto the end of a hinged arm29 mounted in a support 30. which. is secured on top of the T fitting 21. i f

The end of said. ad.'ust1ng.screw 28 extends through a' hole insaid-support 30 and the T fitting 2l and engages the upper side of the discharge end of the tube 23 for the purpose of pressing the same downward against the spring of said tube 23; said screwy being locked in any desired position bythe lock nut 34; andit lwill be seen that the weight of said screw and the arm 29 4are sufiicient t o depress the end of said tube 23 to its'lowestpont or limit.

To overcome this and'to render the device automatic there is-placed' between the hinged arm 29and the support 30 athermostatic wafer 31 which will by the changes in temperature raise or lower thearm 29 and the screw 28 allowing the end of the tube 23' to raise to its'normal'position or be depressed by said screw 28 thus changing the 011 level. Referring'to Figure 4;, if it is desired to operate the device by`hand and `retain a vpositive oil level, the wafer 31 removed and a 36 to the pipe 20 with its hooked end eX- hooked shaped lever 35 is pivoted at tending downward.` through a hole in' the pipe 2() and engaging the free end of the tube 23; while the, other end of thelever 35 is adjustably secured to a bracket 37 by a.

ters Patent, is:

In, an oil feeding device for wckless burners of the'cla'ss described, Ain combination with an oil reservoir andA 'a wickless burner, connected by suitable feed piping,

of a, horizontal feed pipe mounted in the feeding system, a4v flexible tube mountedwithin said horizontal pipe at an angle theres with and having its intake end rigidly secured and its" discharge end free to move, means for preventing the flow ofv o il through vsaid horizontal pipe, and means for adjusting the positiono the freeend of said tube within said pipe, for the purpose set forth and substantially as described.

In testimony whereof I hereunto affix my signature.
